Additional Notes

The 12961 is a Philips part number designation for a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12 volts and 5 watts. The Dodge Magnum (2005-2008) uses this bulb for the license plate position.
The 168 is an ANSI standard designation recognized across the United States and Canada, also a T10 miniature wedge bulb rated at 12 volts and 4.9 watts. The Dodge Magnum (1978-1979) uses this bulb for the license plate position.
Both the 12961 and 168 share the T10 miniature wedge form factor, meaning they occupy the same physical bulb family despite carrying different designation systems, one being a manufacturer part number and the other an ANSI industry standard.
The wattage difference between the two bulbs is minimal, with the 12961 rated at 5 watts and the 168 rated at 4.9 watts. Both operate on a 12-volt automotive electrical system.
The W2.1x9.5d base specified for the 12961 is a standardized wedge base type where the figures describe the contact width and pin spacing in millimeters, which determines physical socket compatibility.
Because the 12961 carries a specific manufacturer designation rather than a universal ANSI code, fitment should be confirmed against the W2.1x9.5d base specification rather than the part number alone when sourcing equivalent replacements for the 2005-2008 model years.
